How does the period of a pendulum difference theoretically with angular displacement and mass of ball for simple pendulum?
According to the mathematics and physics of the simple pendulum hung on a massless string, neither the mass of the bob nor the angular displacement at the limits of its swing has any influence on the pendulum's period.
What instrument can be used to measure a circumference of a pendulum bob?
A tape measure is an instrument that measures perimeter. This can be used in the construction industry to measure a room.
Why does the length of the period increase as the length of the pendulum increases?
If this is a homework assignment, please consider trying to answer it yourself first, otherwise the value of the reinforcement of the lesson offered by the assignment will be lost on you.The period of a pendulum increases as it length increases because the verticle distance the bob travels is less, and thus there is less potential energy available to accelerate the bob in its arc. Also, recall that in vector mechanics the horizontal force vector due to gravity is a function of the direction the object is constrained to follow, and if the pendulum is longer, that direction is more horizontal, giving the horizontal force vector less of an effect.
Can perpetual motion be achieved using a pendulum in a vacuum?
Yes. In a vacuum, the only resistance is the friction in the suspension for the bob of the pendulum. Other than that, it should swing a long time. In air, friction with air will add to the friction in the suspension and it won't swing as well as it would in a vacuum. But it will swing for a while. A pendulum will swing in water, but the hydrodynamic drag will make it stop in a really, really short period of time. Just a couple of swings will strip the pendulum of almost all its energy. And the speed of the pendulum will be slower than in air, and it won't swing anywhere nearly as far through the bottom of its arc as it did in air.
How do you get an ice cube to sink?
Ice can't sink hunny :) It is less dense then water (density= 1.0) and therefore, it can only float, not ever sink.
What is a pendulum bob?
The bob is the weight on the end of the pendulum.
What is the bob of a pendulum?
The bob is the weight at the end of the pendulum. For example, in a grandfather clock the ball at the end of the stick is the bob.
Errors in a simple pendulum and ways of minimizing or reducing the error?
making timings by sighting the bob past a fixed reference point (called a 'fiducial point')Sighting the bob as it moves fastest past a reference point. The pendulum swings fastest at its lowest point and slowest at the top of each swing.· The bob of the pendulum was displaced with a small angle· The amplitude of the oscillation of a simple pendulum is small.· The simple pendulum oscillates in a vertical plane only.· Switch off the fan to reduce the air resistance
The weight on a pendulum is called?
The weight on a pendulum is a 'mass' or a 'bob'.
Does the period of simple pendulum depend on the mass of the bob?
Not in the theoretical world, in the practical world: just a very little. The period is determined primarily by the length of the pendulum. If the rod is not a very small fraction of the mass of the bob then the mass center of the rod will have to be taken into account when calculating the "length" of the pendulum.
What happens to time period of a simple pendulum if a heavy body is attached to it instead of bob?
The period of a simple pendulum is independent of the mass of the bob. Keep in mind that the size of the bob does affect the length of the pendulum.
WHAT IS the term for the mass at the end of a pendulum?
The mass at the end of the pendulum is the bob
What does a Ellicott Pendulum measure?
An Ellicott pendulum is a temperature compensated clock pendulum. The metal rod of a pendulum changes its length with temperature. The consequence is, that a colder pendulum swings faster (the rod is shorter) and a warm pendulum swings slower (longer rod). The Ellicott pendulum compensates this temperature error of the pendulum. It consists of a steele rod and two brass rods, wich are connectet in one point above the pendulum bob. Brass has a higher temperature coefficient than steele. On the free end of the three rods, a special lever mechanism, controlled by the lenght difference of the rods, lifts the pendulum bob up, when the length of the rods grows. The bob stays at its position and the period of the pendulum is without temperature influence. See also http://commons.wikimedia.org/wiki/File:Ellicott_pendulum.png
What is meant by bob in physics?
I THINK BOB REFERS TO THE BALL IN THE PENDULUM
What are the parts of a pendulum?
There are three parts to a pendulum. The bearing, the bob, and the string or wire supportig it.
What does a pendulum bob look like?
A bob is the weight on the end of a pendulum. It can take any shape, but is most often depicted as being round.
Rosa's family has a grandfather clock with a pendulum The clock is not keeping time correctly because the pendulum is swinging too quickly What could Rosa do to slow down the pendulum swing?
To slow down a swinging clock pendulum, one must make it longer. In mechanical clocks, the majority of the mass of the pendulum is contained in the "bob" (a disk or weight) usually at the bottom of the pendulum. If you lower the pendulum bob, the pendulum is lengthened and the pendulum runs slower. This is usually done by turning a nut on a threaded portion of the pendulum just below the bob. Make sure the bob drops as you lower the nut or nothing will change. To raise the rate of the pendulum (make it run faster), you just turn the nut the opposite way.
